Improvement in sugar-cane mills



a ,time 'i ate-ut WILLIAM AIKIN AND Wm-LIAM BENNETT, OFLOUISVILLE-KENTUCKY, (SAID BENNETT AS ADMINISTRATOR OF 'I ESTATE OF J.It. GATES, DEOEASED,) 'ASSIGNORS TO J. F. PEAB-SON AND WILLIAM AIKIN, OFSAMEPLACE.

Letters Patent No. 85,984, dated January 19, 1869.

To all whom 'it may concern.-

Be it known that WILLIAM A Ixnv, and J. R. GATES, now deceased, ofLouisville, in the countyr of Jefferson, and State of Kentucky, didinvent a new and improved Sugar-Cane Press; and we, the said WILLIAMAIKIN, and WILLIAM BENNETT, administrator of the estate of the said J.R. GATES, deceased, do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawingsforming part of this specification, in which-Figure lrepresents a side elevation, partly in section, of this improvedsugar-mill.

Figure 2 is a horizontal section of the same, taken on the plane of theline x x, g. l, the view being inverted.

Figure 3 is a plan or top view of the same.

Figure 4 is a detail top view of one of the rollers, showing the kind ofclutch used to drive it. I

Figure 5 is a detail horizontal section of one ofthe jm-nalboxes, theplane of section being indicated by the line y y, iig. l.

Similar letters of reference indicate corresponding This inventionrelatesto certain improvements in sugar-cane mills, and has for itsobject to simplify the construction of the whole apparatus, andespecially to provide adjustable and good bearings for the rollers, andfacilities for lubricating and repairing the same.l

The invention consists in the application of removable journals, whichare also made adjustable horizon tally, by means of screws, to increaseor relieve the pressiue.

The invention consists, also, in the application of a yielding scraper,for cleaning the roller, and in a new means for retaining the grease inthe lower journals.

A, in the drawing, represents the shell of this 'irnproved sugar-mill.

B is the upper, and

O, its lower head.

I) E F are the three rollers for compressing the cane, and extractingthe juice therefrom.

The axle a of the large rollerI) fits into blocks, that are iitted intoapertures formed through the two heads B O. The blocks are perforated toreceive the axles.

. The axles b l1 of the rollers EF are fitted into similar blocks, cc,'that tit into apertures formed through the heads B C.

The blocks in the top plate B are pertbrated, to allowlubricating-matter to be p'ut in from above, While those in the bottomplate have only sockets for the axles, so that they will retain the oil.

The receptacles for these blocks are enlarged by flanges d d, projectingfrom the heads, as shown in figs. l, 3, and 4.

The blocks are somewhat smaller than the boxes in which they are held,and are, by means of set-screws, e e, regulated, so that they may carrythe rollers more or less together, to obtain the desired effect upon the132MB.

. in the mill, as set forth. 4

the juice of the cane from coming in contact with the oil orlubricating-matter.

The apertures in the blocks c may be elongated, as shown in lig. 5, sothat the` rollers may have slight play in them. Q V

The blocks c are covered by slides y g, which are dovetailed into theupper anges d, as shown in figs. 3 and 1.

By removing the cover g, the block c, protected by it, can be removed,repaired, or the journals can be lubricated.

The large roller, D, receives direct rotary motion by means of a crankor lever, G, on its axle a.

On its upper end are formed lugs, thatmesh into a toothed wheel, h,which lits loose around the axle a.

This wheel gears into pinions t' i, thatv lit loosearound the axles b ofthe rollers E F, and imparts motion to them. j The wheels t' have lugs jformed on' their under sides, that catch against lugs It, projectingfrom the rollers', as indicated in iigs. 1 and 4, and the said rollersare thus revolved as long as the wheels rest on the rollers, 'but when,by the accumulation of matter within, the case should become lilledythewheels will, by said matter, be raised off the rollers, andwill therebythrow the same out of gear. j

H is a scraper, pivoted in the heads B C. Its axle or pivot-pin projectsthrough the upper head, and has an arm, l, between the end of which anda flange, d, a rubber spring, m, is interposed, so that thereby the saidscraper is made yielding and elastic.

The edge of the scraper rests against the periphery of one of therollers, and there may be as many Scrapers used as there are rollers.

Ne claim as new, and desire to secure by Letters Patentp l. Thecombination of the perforated blocks c, the flanges d, sliding covers g,and set-screws c, substantially as described, for the purpose specied.

2. The lower head C, constructed as described, cast with the outergrooved flanges d, for the reception of the blocks c and sliding coversg, and with the inner circular flanges f supporting the rollers, asherein set forth and shown.

3. Driving the rollers E F by means of pinions i i, that fit loosearound their axles, and arc connected by clutches with the rollers,substantially as described, for the purpose of preventing theaccumulation o1 matr-er WILLIAM AIKIN. WM. BENNETT, Administrator of J.R. Gates. Witnesses:
